NASA | Imported Dust in American Skies

The video discusses aerosols, airborne particles that include pollution, dust, and natural elements. It highlights NASA's findings that half of the aerosols above North America are foreign, mostly dust, and high in the atmosphere, thus not directly affecting air quality. The video emphasizes the need to focus on local pollution control and explores how aerosols impact weather, climate, and global atmospheric conditions. It concludes with the message that aerosols have a worldwide impact, affecting climate and air quality across borders.

How do imported aerosols affect the Earth's atmosphere and climate?

What is the take-home message regarding the influence of countries on each other's air quality?
